The coronavirus could cause 63 percent of nonprofits in Massachusetts to have a decrease in revenue, according to a recent survey by the Massachusetts Nonprofit Network.

Out of the 950 nonprofits surveyed, 92 percent reported having to cancel or postpone a fundraising event because of the coronavirus. The nonprofit sector in Mass. makes up nearly 18 percent of the state’s workforce. As the virus continues to force nonprofits to cancel these events, there could be severe consequences for both the causes that need the money and the thousands of people employed at nonprofits.

Bryan Rafanelli, an event planner who helps organize fundraising events for nonprofits like UNICEF, American Red Cross, and the Boys and Girls Club of Boston, told Jim Braude on WGBH News’ Greater Boston Thursday night that nonprofits will have to “plan for the worst.”

“You just have to take stock of what do you have, what do you need, and who can help you, because in this climate you can not be afraid to ask; you have to ask,” he said.

Rafanelli said he is also looking into alternatives to traditional fundraising events.

“We are talking about virtual events. We’re talking about a plan B,” he said.
